to disable only ioctl calls, but preserve tstamp_type assignments.

When the first client of plugins such as dshare open the hw device they set
a default tstamp_type in snd_pcm_direct_initialize_slave based on
tstamp_type from the config file. But when subsequent clients open the same
plugin the snd_pcm_hw_open_fd function clobbers this default.

Install of the alsalisp binary has been disabled since 2006 (in commit
8d382ccd), and building of it was disabled by default in 2018 (in commit
32ceab21), so it is reasonable to assume that nobody is using it.
Use within the alsa-lib project is limited to an aliases file that looks
like it is intended as an example, plus some very small .alisp files
associated with the SiS SI7018 PCI sound card which has not been
manufactured in years. These too have not been installed since 2018 when
commit 32ceab21 disabled building of the alsalisp binary.
In preparing this change, I searched the Github issue tracker for
"lisp", "alisp" and "alsalisp", and found no complaints about the above
changes. I also did a Github code search for projects that might be
including the `alisp.h` header and found none. Therefore I think this
code can be safely deleted and nobody is likely to object.

The values SNDRV_XXX are used incorrectly in some code where they
should have been SND_XXX, due to copy&paste from the kernel code.
Practically seen there are no difference, and the code still works
fine, but those should be corrected for consistency.

In snd_seq_create_ump_endpoint(), it was forgotten to give the UMP
Endpoint capability bit (SND_SEQ_PORT_CAP_UMP_ENDPOINT) to the port 0
("UMP 2.0"). This resulted in port 0 being a normal port for the
non-existing group.

It may be useful to check additional sysfs parameters like USB descriptors
to determine the exact hardware capabilities.
Introduce 'sys-card' substitution and 'sys' substitution to allow data
fetching from given range. Also, add conversion to hexadecimal format
when the source file has binary contents.
Example - fetch bytes from positions 0x10..0x15 (6 bytes):
Define.Bytes1 "${sys-card:[type=hex,pos=0x10,size=6]device/../descriptors}"
Example - fetch one byte from position 0x22:
Define.Bytes2 "${sys-card:[type=hex,pos=0x22]device/../descriptors}"
Replace type=hex or omit this variable settings to work with ASCII
characters.

Fixes several issues with header files:
- prefer alsa/asoundlib.h file for the alsa-lib core functionalities
(use #warning to inform current and future developers, do the job)
- include alsa/asoundlib.h in headers for external plugins by default
- pcm_external.h: dependencies cleanup
- as benefit, the parsers in IDEs should get all information for individial
header files (see PR#435)
This change was mainly tergetted to fix errors caused by wrong include order
(like for endianness detection, missing typedefs etc.).
